Abstract:
Type II supernovae (SNe II) mark the endpoint in the lives of
hydrogen-rich massive stars. Their large explosion energies and
luminosities allow us to measure distances, metallicities, and star
formation rates into the distant Universe. To fully exploit their use
in answering different astrophysical problems, high-quality
low-redshift data sets are required. Such samples are vital to
understand the physics of SNe II, but also to serve as calibrators for
distinct - and often lower-quality - samples.
We present uBgVri optical and YJH near-infrared (NIR) photometry for
94 low-redshift SNe II observed by the Carnegie Supernova Project
(CSP). A total of 9817 optical and 1872 NIR photometric data points
are released, leading to a sample of high-quality SN II light curves
during the first 150 days post explosion on a well-calibrated
photometric system.
The sample is presented and its properties are analysed and discussed
through comparison to literature events. We also focus on individual
SNe II as examples of classically defined subtypes and outlier
objects. Making a cut in the plateau decline rate of our sample (s2),
a new subsample of fast-declining SNe II is presented.
The sample has a median redshift of 0.015, with the nearest event at
0.001 and the most distant at 0.07. At optical wavelengths (V), the
sample has a median cadence of 4.7 days over the course of a median
coverage of 80 days. In the NIR (J), the median cadence is 7.2 days
over the course of 59 days. The fast-declining subsample is more
luminous than the full sample and shows shorter plateau phases. Of the
nonstandard SNe II highlighted, SN 2009A particularly stands out with
a steeply declining then rising light curve, together with what
appears to be two superimposed P-Cygni profiles of H in its spectra.
We outline the significant utility of these data, and finally provide
an outlook of future SN II science.
Description:
The data presented in this paper were acquired through the CSP
over two distinct observational SN follow-up programmes.
CSP-I (Hamuy et al. 2006PASP..118....2H 2006PASP..118....2H) operated between 2004 and
2009 and obtained data for 74 SNe II.
